System and method for creating conditional immutable objects in a storage device

ABSTRACT

A data storage system includes a storage device and a data handler that receives an object, creates metadata for the object that includes a key and an authorization, stores the object on the storage device, receives a request for the object, determines if the request includes the key, and, if the request has authorization information, permits access to the object. The data handler receives another request for the object, determines if the request includes the key, and, if the request does not have the authorization information, denies access to the object.

FIELD OF THE DISCLOSURE

This disclosure relates generally to information handling systems, and relates more particularly to conditional immutable data storage in an information handling system.

BACKGROUND

As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option is an information handling system. An information handling system generally processes, compiles, stores, or communicates information or data for business, personal, or other purposes. Because technology and information handling needs and requirements can vary between different applications, information handling systems can also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information can be processed, stored, or communicated. The variations in information handling systems allow information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems can include a variety of hardware and software resources that can be configured to process, store, and communicate information and can include one or more computer systems, data storage systems, and networking systems.

Regulatory requirements for data retention may require that certain information be maintained as immutable data at one time, but that the same information must be deleted at a later time. For example, regulations may require that employment records for an employee be stored permanently while the employee is employed, but the regulations may also require that the records be deleted within a certain time after employment ceases. An information handling system may include a Write-Once Read-Many (WORM) data storage systems to permanently retain data.

DETAILED DESCRIPTION OF DRAWINGS

The following description in combination with the Figures is provided to assist in understanding the teachings disclosed herein. The following discussion will focus on specific implementations and embodiments of the teachings. This focus is provided to assist in describing the teachings, and should not be interpreted as a limitation on the scope or applicability of the teachings. However, other teachings can be used in this application. The teachings can also be used in other applications, and with several different types of architectures, such as distributed computing architectures, client/server architectures, or middleware server architectures and associated resources.

An information handling system can include a data storage system. In a particular embodiment, described herein, a host processing system writes data to, and reads data from the data storage system. The data storage system provides immutable data storage functionality, mutable data storage functionality, and conditional immutable data storage functionality for the information handling system. A non-limiting example of a data storage system includes disk memory, non-volatile random access memory such as FLASH or other non-volatile storage, another data storage system, or a combination thereof.

FIG. 1 illustrates a data storage system 100 according to an embodiment of the present disclosure, including client processing systems 110 and 115, a data handler 120, and a storage device 130. Storage device 130 includes a storage controller 132 and a storage medium 134, and can include other storage media (not illustrated). Client processing systems 110 and 115 are connected to data handler 120, and data handler 120 is connected to storage device 130. Client processing systems 110 and 115 are adapted to transfer data to and from storage device 130 over an interface such as a Small Computer System Interface (SCSI), a Peripheral Component Interconnect Express (PCI Express) interface, or another data communication interface.

Client processing systems 110 and 115 represent various users of the storage space on storage device 130. As such, client processing systems 110 and 115 can include one or more applications operated on an information handling system and that utilizes storage resources while running the application. For example, client processing systems 110 and 115 can include an e-mail processing environment with applications and servers available to process and store e-mail data, a database system operating to run one or more databases, a custom application such as a medical records system or human resource record system, another operating environment, or a combination thereof. Client processing systems 110 and 115 can also include one or more end user information handling systems. For example, client processing systems 110 and 115 can represent a single information handling system operated by a single end user or shared by multiple end users, or can represent a group of information handling systems with a common usage. For example, client processing system 110 can represent a group of managers that have a particular level of access to employee records on a human resource record system, and client processing system 115 can represent a group of human resources personnel that have a different level of access to the employee records.

Data handler 120 represents a shared resource between client processing systems 110 and 115 and storage device 130. Data handler 120 interacts with client processing systems 110 and 115 to process storage requests to read or write data to storage device 130, and interacts with storage device 130 to process the requests. Data handler 120 receives write requests from client processing systems 110 and 115. The write requests include an object that is to be written to storage device 130. Data handler 120 also receives read requests from client processing systems 110 and 115 to retrieve objects that have been previously written to storage device 130. Data handler 120 further receives delete requests from client processing systems 110 and 115 to delete objects that have been previously written to storage device 130. In each case, data handler 120 forwards the write requests, read requests, and delete requests to storage device 130. Data handling system 120 can be implemented as a hardware device, as a module of an information handling system, as an information handling system, or a combination thereof.

Storage device 130 represents a data storage device such as a direct-attached storage (DAS) system, a network-attached storage (NAS) system, a storage-area network (SAN), another storage device, or a combination thereof. Storage controller 132 receives the write requests, read requests, and delete requests from data handler 120, takes appropriate action to store, retrieve, or delete objects from storage medium 134, and provides the appropriate response back to data handler 120. FIGS. 2-4 include flowcharts showing how storage controller 132 responds to a write request 200, a read request 300, and a delete request 400. In FIG. 2, illustrating write request 200, storage controller 132 receives an object from data handler 120 in block 212. The object is streamed to storage media 134 in block 214, and the stream is written on storage media 134 in block 216. When the object is successfully written to storage media 134, a universally unique identifier (UUID) is generated by storage controller 132 and sent to data handler 120 in block 218. The UUID is associated with the location where the object is stored on storage media 134.

In FIG. 3, illustrating read request 300, storage controller 132 receives a UUID in block 312. The UUID is associated with the location of an object that is stored on storage media 134. Storage controller 132 determines the location associated with the UUID and initiates a stream read from storage media 134 in block 314. The object is read from storage media 134 in block 316, and the object is sent to data handler 120 in block 318.

In a particular embodiment, storage device 130 functions to provide immutable data storage, such that data, once written to storage media 134, cannot be overwritten or deleted. For example, storage media 134 can be implemented as a Write-Once Read-Many (WORM) storage device. In another embodiment, storage media 134 can include portions of the retained data that is immutable, while other portions of the retained data remain mutable. When some or all of storage media 134 includes immutable data, the delete request 400 is performed, as illustrated in FIG. 4. Storage controller 132 receives a UUID from data handler 120 in block 412. Storage controller 132 determines if the location associated with the UUID is immutable in decision block 414. If so, then the “NO” branch of decision block 414 is taken, indicating that the delete request is invalid, and storage controller 132 indicates that the delete request resulted in a failure to data handler 120 in block 416. If the location associated with the UUID is not immutable, then the “YES” branch of decision block 414 is taken, indicating that the delete request is valid, and the associated stream is deleted from storage media 134 in block 418. Storage controller 132 then indicates that the delete request 400 resulted in a success to data handler 120 in block 420.

In another embodiment, data handler 120 operates to provide three types of data storage on storage device 130, including immutable data, mutable data, and conditional immutable data, in addition to flexible mechanisms of controlling access to stored data. Immutable data is data that is intended to be retained indefinitely. Thus, once immutable data is written to storage media 134, subsequent modify or delete requests result in a failed request. Mutable data is data that can be overwritten or deleted. Conditional immutable data is data that is treated as immutable data in some circumstances, and treated as mutable data in other circumstances. For example, a particular object can be treated as immutable when accessed by client processing system 110, but can be treated as mutable when accessed by client processing system 115. In another example, a time limit can be placed on a particular object, such that before the time limit is expired, the object is immutable, but after that time the object is mutable.

FIG. 5 illustrates a data object 500 that provides for conditional immutable data operations on data storage system 100, including object content 510 and object metadata 520. Object content 510 includes the content data provided from client processing systems 110 or 115 for storage in storage device 130. Object metadata 520 is information added to data object 500 by data handler 120 that provides for keyed conditional access to data object 500 and for authorization of access to the functions of data storage device 130. Object metadata 520 includes an authentication key 522 and an authorizations field 524.

Authentication key 522 provides a field for authenticating access requests to object content 510 in data object 500. Here, on creation of data object 500, data handler 120 determines a value for authentication key 522 to append in object metadata 520. After data object 500 is stored on storage device 130, requests to access data object 500 include an authentication key that is compared with authentication key 522. If the value of the provided authentication key matches the value of authentication key 522, then access to data object 500 as given in authorization field 524, described below, is granted. If the value of the provided authentication key does not match the value of authentication key 522, then access to data object 500 is denied. For example, data handler 120 generates authentication key 522 to append with object metadata 520 when object content 510 is to be written to storage device 130. For example, data handler 120 can generate a UUID associated with object content 510, and append the UUID as authentication key 522. Other examples include providing an authentication number using another securely generated identification number or other identification mechanism. In another embodiment, client systems 110 or 115 can provide an identification mechanism, a password, another means of identifying with object content 510, or a combination thereof.

Authorizations field 524 describes the actions permitted on data object 500. In a particular embodiment, authorizations field 524 includes one or more type authorization bit-fields 526. Type authorization bit-field 526 includes a type field 530, and operation fields 540. Each operation field 540 includes a key enabled field 542 and a keyless enabled field 544. Type field 530 indicates a particular feature or type of access to which the authorizations in operation fields 540 apply. For example, type field 530 can indicate that members of a particular group have the specified access, that access to the specified authorizations applies until a particular time, that access to the specified authorizations applies based upon another type of feature or type, or a combination thereof.

Operation fields 540 indicate whether or not a write access, a modify access, a read access, or a delete access is permitted when authentication key 522 is present, as indicated by the value of the associated key enabled field 542. Operation fields 540 also indicate whether or not a write access, a modify access, a read access, or a delete access is permitted when authentication key 522 is not present, as indicated by the value of the associated keyless enabled field 544. In a particular embodiment, a logic “1” can indicate that the associated feature is enabled. Thus, for example, a logic value of “1000 1110” would indicate that a write operation on storage device 130 is permitted only with an authorization key, a modify operation is not permitted, either with or without the authorization key, a read operation is permitted with or without the authorization key, and a delete operation is only permitted with an authorization key. In another embodiment (not illustrated), object metadata in a data object can include multiple authentication keys and multiple authorizations, thus different authorizations can be applied based upon the presence of different authentication keys.

FIGS. 6-9 include flowcharts showing how data handler 120 sends a write request 600, a modify request 700, a read request 800, and a delete request 900 to storage device 130, and the actions taken to store, modify, retrieve, or delete objects from storage medium 134. In FIG. 6, illustrating write request 600, storage controller 132 receives an object including object data and object metadata from data handler 120 in block 612. The object is streamed to storage media 134 in block 614, and the stream is written on storage media 134 in block 616. When the object is successfully written to storage media 134, a UUID is generated and sent to data handler 120 in block 618.

In FIG. 7, illustrating modify request 700, data handler 120 sends a UUID to storage controller 132 in block 712. The UUID may or may not include an authentication key. In response to receiving the UUID, storage controller 132 streams the metadata from the object associated with the UUID to data handler 120 in block 714. A decision is made as to whether or not the key provided in the UUID matches the key in the metadata in decision block 716. If not, the “NO” branch of decision block 716 is taken, and a modify failure is indicated in block 724. If the key provided in the UUID matches the key in the metadata, the “YES” branch of decision block 716 is taken, and a decision is made as to whether a modification to the object is authorized in decision block 718. If not, the “NO” branch of decision block 718 is taken, and a modify failure is indicated in block 724. If a modification to the object is authorized, the “YES” branch of decision block 718 is taken, the object is modified on storage media in block 720, and a modify success is indicated in block 722.

In FIG. 8, illustrating read request 800, data handler 120 sends a UUID to storage controller 132 in block 812. The UUID may or may not include an authentication key. In response to receiving the UUID, storage controller 132 streams the metadata from the object associated with the UUID to data handler 120 in block 814. A decision is made as to whether or not the key provided in the UUID matches the key in the metadata in decision block 816. If not, the “NO” branch of decision block 816 is taken, and a read failure is indicated in block 826. If the key provided in the UUID matches the key in the metadata, the “YES” branch of decision block 816 is taken, and a decision is made as to whether a read of the object is authorized in decision block 818. If not, the “NO” branch of decision block 818 is taken, and a read failure is indicated in block 824. If a read of the object is authorized, the “YES” branch of decision block 818 is taken, the object is read from storage media in block 820, and a read success is indicated in block 822.

In FIG. 9, illustrating delete request 900, data handler 120 sends a UUID to storage controller 132 in block 912. The UUID may or may not include an authentication key. In response to receiving the UUID, storage controller 132 streams the metadata from the object associated with the UUID to data handler 120 in block 914. A decision is made as to whether or not the key provided in the UUID matches the key in the metadata in decision block 916. If not, the “NO” branch of decision block 916 is taken, and a delete failure is indicated in block 924. If the key provided in the UUID matches the key in the metadata, the “YES” branch of decision block 916 is taken, and a decision is made as to whether a deletion of the object is authorized in decision block 918. If not, the “NO” branch of decision block 918 is taken, and a delete failure is indicated in block 924. If a delete of the object is authorized, the “YES” branch of decision block 918 is taken, the object is deleted from storage media in block 920, and a delete success is indicated in block 922.
